There have been plenty of articles detailing which Doctor Who actors have shown up in the Harry Potter films and vice versa, but have you ever thought about what would happen if these two beloved worlds actually merged?

Accio the “Doctor Potter” meme! This brilliant Tumblr mash-up makes the perfectly reasonable case for the Doctor and his latest companion to drop the TARDIS into the wizarding world. The GIFs and photo manips are so expertly done that you can almost giddily imagine that this is a lost episode.

I came across these mesmerizing GIFs yesterday, of Daleks and other baddies laying siege to Hogwarts. It’s difficult to look away, partly because the editing is so crisp. But also because seeing the TARDIS on the Hogwarts grounds is one of those things that you never realized fit so well until someone made it so.

But while the above GIFs craft a pretty dark and dramatic narrative, mostly the “Doctor Potter” tag is a series of one-offs. The Silence pop up over and over as a punchline in this meme, probably because they most resemble a Potterverse creature.

Even more popular is the TARDIS. Maybe because we’re already used to Harry and friends traveling through the wizarding world via portkeys and Floo powder, it doesn’t seem so strange to envision a blue police call box peeking out of the Tri-Wizard Tournament hedge maze (via zettephrasie), or spiriting our favorite characters away from harm.
